Iecc where no pressure difference relative to the surrounding air is present. Degrees of protection listed in this table shall be specified only by the second. If you have any query regarding testing and Certification. For tests on low-voltage equipment, a low-voltage supply of not less than 40 V and not more than 50 V in series with a suitable lamp should be connected between the probe and the hazardous parts inside the enclosure.

Iecc where no pressure difference relative to the surrounding air is present. Degrees of protection listed in this table shall be specified only by the second. If you have any query regarding testing and Certification. For tests on low-voltage equipment, a low-voltage supply of not less than 40 V and not more than 50 V in series with a suitable lamp should be connected between the probe and the hazardous parts inside the enclosure.

In no shall the depression exceed 2 kPa 20 mbar on the manometer shown in figure 2. The counterbalanced shield is removed from the spray nozzle and the enclosure is sprayed from all practicable directions. The test shall be continued for a period of 8 h.

Extremely Versatile — fully Waterproof and Portable! See annex A for further clarification. The talcum powder used shall be able to pass through a square-meshed sieve the nominal wire diameter of which is 50 jim and the nominal width of a gap between wires 75 jim. If there are other holes for example, more cable inlet holes or drain-holes these shall be treated as intended for normal use on site. Immersed at depth of eic effect of temporary immersion in waterIPX8Immersed in depth mentioned by manufacturerThe effect of continuous immersion in waterIPX9-High pressure and water jets.

Copyright BIS has the copyright of all its publications. The first digit shows the to which the equipment is protected against particles, or to which persons are protected from enclosed hazards. For enclosures without drain-holes, the relevant product standard shall specify the acceptance conditions if water can accumulate to reach live parts.

The amount of talcum powder to be used is 2 kg per cubic metre of the test chamber volume. Where more than one supplementary letter is used, the alphabetic sequence shall apply. If it is impracticable to make a special hole, the suction connection shall be made to the cable inlet hole. Product Details For testing the protection against moisture due to splashing water.

Internal moving parts may be operated slowly; where this is possible. Enclosures where the normal working cycle of the equipment causes reductions in air pressure within the enclosure below that of the surrounding air, for example, due to thermal cycling effects. Related Posts.
